As for Christian’s advice for Ben, it was centered on making sure everything gets out of the Batcave in an easy and timely manner.

“[I told him] just make sure you can take a piss without anyone helping him ‘cuz it’s a little bit humiliating,” the actor told Access. “I went through having to have someone help you out of the costume in order to be able to do that. That was main piece of advice for him.”

Christian’s “Out of the Furnace” co-star and Ben’s younger brother, Casey Affleck, also weighed in on Ben playing the Caped Crusader.

“He’s got a lot to live up to… [there’s] a long line of great actors he’s following, so I’m sure he’ll do fine though… he’ll do great,” Casey said, adding that he thinks Ben will “look good” in the Batsuit.
